clone: rename "rev" to "revs" since there can be many
It was a little tricky in hg.clone(), since there was a local "revs"
variable defined there, but "rev" was never used after "revs", so I
just overwrote it.
Note that clonewithshare() should also have its "rev" argument renamed
to "revs", but I'll leave that to someone else.
